Hi all,

How come the following XPath expression doesn't return any nodes?

descendant::*[node()=SignerInfo]

Here's how it's called on the document root node:

XmlNodeList list = m_xmlDoc.DocumentElement.SelectNodes(sXPathExpression);
Here's the XML:

<?xml version="1.0" encoding="utf-8"?><Deal BPApplication="WCC"

Thanks a lot!

P.S.

Sorry, I think outlook express messed up the xml when pasted.

That's sort of weird expression, but it should work though. What do you
want to select actually? If you want to select an element which has
SignerInfo child, use descendant::*[SignerInfo], if you want to select
SignerInfo element at any level, use descendant::SignerInfo.

Thanks for your response Oleg,

I know the expression can be specified in a simpler way, but the problem I
have is that even the
expressions you suggested don't work with XPath on .net 1.1 and the _xml
document that I included_.

If I use the same code against a different xml document (i.e. one formatted
like an XmlDataDocument)
then those expressions work. So I was wondering if there is a
problem/limitation with .net 1.1 XPath support?

Thanks,
--Ader.
